Diesel enthusiasts’ interest in engine swaps is at an all-time high, spurred on by owners’ love of their aging vehicles and disenchantment with the performance of their factory-installed powerplants or the desire to drive something a little different from the norm. Converting from gas to diesel or from one brand of oil-burner to another is also enticing because of the ever-increasing availability of adapters, kits, standalone computers, and wiring harnesses that facilitate using various modern diesel-repower combinations to fit a wide variety of trucks and SUVs.
The diesel-engine mating game has never been more fine-tuned. If you want to repower an older Jeep, Ford, Chevrolet, or Toyota with a Cummins engine, there are sources for the engines, adapters, and complete conversion kits that make it happen. You want to drop a Duramax-Allison engine/transmission package into a square-nosed GM pickup from the ’70s and ’80s? How about sliding an Allison gearbox behind a Cummins in a Dodge Ram or a Cummins into a Ford Super Duty? Does installing a turbocharged Kubota in a Willys or a Mercedes-Benz diesel in a Jeep Cherokee sound appealing? If you answered “yes,” there’s a conversion company or parts available to make it happen.
Performing a diesel-engine swap isn’t easy. It takes time, knowledge, and patience. As any conversion specialist will tell you, the level of difficulty entirely depends on the make/model of the engine, the transmission being used, and the vehicle that’s being repowered. With pre-computer era vehicles, a set of engine mounts and a few adapters can put you on the right path very quickly, followed by whatever fabrication, wiring, and welding necessary to get fuel delivery, cooling, and exhaust systems sorted out.

But when engine and transmission computers are part of the equation (as they are on most ’90s-and-newer trucks and SUVs), the difficulty level ramps up considerably as drivetrains are crossbred. Fortunately, so many diesel-engine swaps have been executed over the last two decades that today’s repower experts have developed plug-and-play wiring harnesses, standalone computers, and complete conversion kits to mix and match popular powerplants and transmissions so they function as well as factory-installed hardware.
Performing a diesel swap usurps a big chunk of time. A DIY enthusiast with a good knowledge of diesels—and who is adept at welding, wiring, plumbing, and fabrication—can usually pull off a basic gas-to-diesel or diesel-to-diesel swap in 40 to 60 hours. Those who yearn to bolt a diesel into their rig but are either a little lacking on the mechanical aspects or short on time, can turn to shops that specialize in turnkey conversions to handle the work.
The key to smiling when you hear that distinctive engine purr of a successfully executed diesel conversion is doing a lot of research to get everything lined up before a wrench is turned. First, check with your state’s department of motor vehicles to find out the requirements for re-registering a gas vehicle as diesel or to make sure you know the regulations pertaining to engine swaps. The general rule is you can’t install an engine that’s older than the year of the vehicle if that engine is required to meet a state’s smog laws.
So, with all other ducks in a row, it’s on to parts and services. To help speed up that part of the repower process, check out our overviews. We found more than two dozen companies that can help smooth the way for your diesel repower. We’ve highlighted their areas of specialty and hope this guide will help you execute a successful diesel swap for your rig.

Cummins Repower

Converting older vehicles with Cummins 3.9L 4BT and 5.9L 6BT diesels has been popular for decades, because the engines are well-known for their simplicity, efficiency, availability, and reliability. But they are old and not really that well suited for fitting under the hoods of lighter pickups, such as the Nissan Frontier, Toyota Tacoma, and Ford Ranger, or SUVs, such as Jeeps, Ford Bronco IIs, Toyota 4Runners, Land Rovers, and Range Rovers.

Enter Cummins Repower’s turnkey R2.8L turbodiesel engine. It’s ideal for retrofits into Jeeps, compact pickups, smaller SUVs, or any vehicles with less than a 4,000-pound curb weight. The high-tech, electronically injected common-rail R2.8L I-4 weighs just 503 pounds and makes 161 hp at 3,600 rpm, with 267 lb-ft of torque at 1,800 rpm. (With tuning only, shops such as Bruiser Conversions are already seeing 225 hp and 415 lb-ft of torque from R2.8Ls they’ve put in Jeeps.)
That’s in comparison with the 3.9L 4BT, which tips the scales closer to 750 pounds while producing nearly identical torque and 50 percent less horsepower than the stock R2.8L. When it comes to conversions, the bulky 4BT is a pain to install, while the compact R2.8L is pretty much drop-in, plug-in, and turnkey.
The ready-to-run Tier 1 crate engine, which retails for $8,999, is a 50-state-legal, E.O.-certified package. It includes the ECM, throttle pedal and cable, CAN display, OBD II port, firewall bulkhead connector, dashboard-integration wiring harness, starter, vacuum pump, power-steering pump, alternator, eight-rib belt and pulleys, remote oil and fuel-filter systems, and universal bracket to mount air-conditioning equipment. All this diesel needs to run is fuel, 12 volts, the appropriate cooling system, and a suitable frame to call home.
As of this writing, the Cummins R2.8L crate offering is by far the biggest blip on the repower radar, with many customers waiting for a backlog to end. Just wait until Cummins makes the 5.0L V-8 that’s currently found in the Nissan Titan XDs a repower option. There’s serious chatter on the rumor mill about that possibility. If it’s true, we believe the diesel-conversion market will really explode!

DIESEL REPOWER RESOURCES
